17 x 36 with baja step (approx. 7' x 12'). 3 1/2' to 7' deep. 8' spa...We have had several pool contractors come out and give us prices. All of them have changed the design a bit but the size of pool has stayed the same. From top of pool area to back of house there is a 6' slope. The drawing I posted has 18" pony wall around back and sides of pool and 36" pony wall with steps at front of pool. Also have 6 pillars with lights around pool. I have a big family so want lots of room around pool for lounge chairs and table. After getting a few prices, we are thinking of a DIY pool/spa. Not sure yet. Any advice is appreciated.
